Abstract
A motorized vacuum brush head for use with a vacuum. The brush head has a body with an air passage passing though it. The face of the brush head faces the surface being cleaned. A rotatable brush and the air passage mouth are on the face. The brush is flat and has an axis of rotation substantially perpendicular to the face. The brush rotates parallel to and substantially co-planar with the face. Several arms of bristles extend radially from the brush's axis of rotation. As the brush rotates, the leading edge of the bristles drive debris toward the mouth, where it becomes entrained in the air stream entering the vacuum. The rotation of the brush in the plane of the face allows the bristles to remain in continuous contact with the surface being cleaned, thereby increasing the efficiency with which the brush head, and by extension, the vacuum clean.
Description
- 1. Field of the Invention
- The invention relates to vacuum attachments in general and to powered hand-held vacuum attachments in particular.
- 2. Prior Art
- Prior art vacuums have brush attachments. Passive or unpowered attachments are common. In these devices, a nozzle is placed at the end of the vacuum intake opening. The end of the nozzle is provided with a brush. The brush is used to scrub the surface being cleaned manually. Debris dislodged by the brush is picked up by the air stream being drawn into the vacuum.
- Powered vacuum brush attachments are also known in the prior art. For example, published U.S. patent application Ser. No. 10/100,727 discloses a powered vacuum attachment with a rotary brush. The powered brush provides obvious advantages over the manual brush in that the operator does not have to manually scrub the surface being cleaned. However, in the type of attachments disclosed in the '727 Application, the brush rotates on drum. Bristles extend generally radially from the drum. As the drum rotates only a small portion of the bristles are in contact with the surface being cleaned at any one time. Thus, much of the brush is not doing work as it rotates. Similarly, the brush is only scrubbing a relatively small area compared to its surface area at any one time. In view of the foregoing, a powered vacuum attachment meeting the following objectives is desired.
- It is an object of the invention to provide a powered brush attachment for a hand-held vacuum.
- It is another object of the invention to provide a powered brush attachment with bristles configured to maintain constant contact with the surface being cleaned during rotation of the brush.
- It is still another object of the invention to provide a powered brush attachment configured to scrub a relatively large area of the surface being cleaned relative to the surface area of the brush.
- It is yet another object of the invention to provide a powered brush attachment provided with bristles configured to direct debris toward the debris intake opening as the brush is rotated.
- It is still another object of the invention to provide a brush attachment powered by the vacuum's internal electrical system.
- The invention comprises a motorized vacuum brush head for use with a vacuum. The brush head has a body and an air passage that passes though it. The air passage engages the air intake of the vacuum so that air is drawn into the vacuum through the air passage. The face of the brush head faces the surface being cleaned. A rotatable brush and the air passage mouth are both position on the face proximate to one another. The brush is flat and has an axis of rotation substantially perpendicular to the face. The brush rotates parallel to and substantially co-planar with the face. In one preferred configuration, several arms of bristles extend radially from the brush's axis of rotation. The arms are preferably curved. As the brush rotates, the leading edge of the bristles drive debris toward the mouth, where it will becomes entrained in the air stream entering the vacuum. The rotation of the brush in the plane of the face allows the bristles to remain in continuous contact with the surface being cleaned, thereby increasing the efficiency with which the brush head, and by extension, the vacuum clean.

Similarly,body 5 may be provided with electrical leads which plug directly into a receiver that is connected toelectrical system 4 ofvacuum 2 whenbody 5 engagesvacuum 2. Of course, all of the foregoing assumes thatbody 5 will be detachable fromvacuum 2, as will be the case in the preferred embodiment. However,body 5 may be permanently or semi-permanently attached tovacuum 2. In such case,motor 17 may be hard wired intoelectrical system 4 ofvacuum 2. - In operation,
vacuum 2 will be utilized to engage and clean a surface, particularly an environmental surface, or that surface which is in the environment ofvacuum 2 and sought to be cleaned. In such case,body 5 will preferably engagevacuum 2 and connect toelectrical system 4.Electrical system 4 will deliver power tomotor 17, thereby causingbrush 11 to rotate whilevacuum 2 draws air intoair intake aperture 3 andair passage 7 viamouth 10. As bristles 11 ofbrush 11 contact the surface being cleaned, bristles 13 will scrub the surface and cause debris to become dislodged from the surface. As bristles 13 rotate, they will drive loose debris towardmouth 10. As debris approachesmouth 10, it will become entrained in the airstream entering mouth 10 and will be drawn intovacuum 2 viamouth 10 andair passage 7 along with the air stream. - In operation,
body 5 will preferably engagevacuum 2 and connect toelectrical system 4.Electrical system 4 will deliver power tomotor 17, thereby causingbrush 11 to rotate whilevacuum 2 draws air intoair intake aperture 3 andair passage 7 viamouth 10.
